Sound reduction index of clay hollow brick walls

Nicola Granzotto, Edoardo Piana, Antonino Di Bella

Abstract: This paper investigates the sound insulation properties of clay hollow brick walls with low void fraction, horizontal/vertical mortar joint and plaster finishing. Methods based on homogeneous walls (Sharp theory and ISO 12354 procedure) are evaluated. A reference curve obtained as the mean of normalised sound reduction index curves measured in laboratory on real brick walls is proposed and its suitability for sound insulation estimations is discussed.
